Solution Overview

Problem

Existing clamp rings for containers require significant force to install and remove, making them user-unfriendly.

Innovation Solution

A clamp ring with an arcuate collar and a clamping mechanism featuring a pull and wheel system that allows for easy installation and removal by turning the wheel to draw the collar end portions together, creating a secure seal between the lid and the container mouth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional clamp ring is used to hold the lid on the container mouth, then the lid is securely retained, but significant force is required to install and remove the lid

Engineering Contradiction:

Improvelid retention securityVSAvoidforce required for installation and removal

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The clamp ring transitions from a static structure to a dynamic one with movable end portions that can be drawn together through the wheel and pull mechanism, enabling easy opening and closing while maintaining secure clamping when closed

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The wheel and pull mechanism serve as an intermediary device that translates small rotational movements of the wheel into large linear movements of the pull, providing mechanical advantage to draw the collar end portions together with minimal user force

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A claim ring for a lid, components thereof, and associated methods. The clamp ring is configured to maintain a lid on a mouth of a container to form a seal therebetween. The clamp ring includes a clamping mechanism including a wheel and a pull. The wheel is turnable to pull the pull to draw end portions of the clamping ring toward each other. A tool receiver can be engaged by a tool and turned by the tool to turn the wheel with the mechanical advantage of the tool.
